Now if you divide just 7 by 3, you get a non-integer that will have to be combined with other integers. So just the 7 as the numerator over the 3 won't work. But 2 + 7 is 9 and that is evenly divisible by 3. But so is 4 times 2 is 8 plus 7 is 15. But 15 divided by 3 is 5 plus 8 is only 13. So let's go back to the 2 + 7 as the numerator. That is 9 divided by 3 is 3. That is really all you have to do because order of operations says multiplication first. 3 times 4 is 12 plus 8 is 20\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( "My calculator said it, I believe it, that settles it \n" ); document.write( " ![]() \n" ); document.write( " \n" ); document.write( " |
